I love a good old charity collaboration, in fact I'm working on one myself right now (all to be revealed soon), but many fall by the wayside because, quite frankly, they aren't that captivating. I know that sounds very shallow, after all it's about giving to that particular charity at the end of the day, but if you are buying something, you want it to be amazing.Well, here's one collaboration that is truly amazing. Wool And The Gang, a knitting collective with people all round the world contributing to their sustainable ethic, and Atterley Road, the online shopping site, have partnered with charity Save The Children and 30 uber cool British designers (including some students from the London College of Fashion) to create unique jumpers for a SECRET SALE as part of the charity's Christmas Jumper Day. When you buy one of these (they go on sale on 3rd December for that day only!), you won't know who has designed it until you receive it! Ohhh I love a secret sale! Everyone from Jonathan Saunders to Mary Katrantzou and Lulu Guinness to Mother of Pearl have designed their very own jumpers. I'm mesmerized by all of them! They're so incredible. Don't forget to put December 3rd in your diaries! Click here and bookmark this page...
